Title: Update pretty-urls.html.markdown

Added clarification that when using the blogging extension, if the blog permalink is set to include a file extension, it will override directory indexes.

Perhaps I'm the only one who had this problem, but the interaction between these parameters is not entirely obvious and I thought I should improve the documentation for anyone who comes after me. :)
